"PC Power & Cooling Silencer 910 uses internally the same design as Seasonic M12D, thus being manufactured by Seasonic. This design is based on a DC-DC converter on the secondary, i.e. Silencer 910 is basically a +12 V power supply with two small power supplies in charging of converting the +12 V output into +5 V and +3,3 V. This is the same concept used on power supplies series like Signature and TruePower New from Antec, M12D from Seasonic, UCP from Cooler Master and HX (750 W and above) from Corsair. These other models proved to have an above-the-average efficiency. It is important to keep in mind that other models from PC Power & Cooling Silencer series use a different internal design. Let's see how the performance from PC Power & Cooling Silencer 910 is."
